Lateritic nickel ore deposits - Wikipedia

Genesis and types of nickel laterites. Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization.

Saprolite is isovolumetrically weathered bedrock that retains the original lithic fabric (Stolt & Baker, 1994). Most tropical landscapes are underlain by these weathered mantles of varying thickness. Saprolite usually reaches down to more than 50 m in humid areas on crystalline rocks, where they form an important part of the regolith.

The production of nickel and cobalt from primary sources involves beneficiation, and hydrometallurgical and pyrometallurgical processing. Nickel is recovered from lateritic oxides either as ferronickel from saprolite ores or as an intermediate mixed sulfide or hydroxides from limonite ores. Sulfide ores are converted into matte. Intermediate products are refined into high-purity nickel.
